There has been a discussion about the idom for nullable boolean checks [here](https://discuss.kotlinlang.org/t/is-the-idiom-for-checking-nullable-booleans-helpful/8238).  
Also the official guidelines say that you should prefer using `someNullableBoolean == true` or `someNulullableBoolean == false` over the elvis operator.
